Sorry for late reply :-)

I want to add the following setting:

" If Vim cause malfunctioning cursor keys on slow terminals or very busy systems, adjust the value or comment out this.
set ttimeoutlen=0

'ttimeoutlen' default value is -1.
This means that use the 'timeoutlen' to the key code time-out value.
That one second.
I think most user feels "Vim is slow" in the following operation. This is disadvantage.
- When the transition to the normal-mode by pressing the XXX in insert-mode.
i<Esc>
- Similarly, in visual-mode.
V<Esc>
- Similarly, in cmdline-mode.
:<Esc>

Yes, I know that lag does not occur if the input without waiting for the display is switched.
But, most people would wait until the display is switched. And they feels "Vim is slow...".

`set ttimeoutlen=0` will solve the above.

I have invested in above setting more than a year, but the trouble does not happen even once.

thanks.
